BCH FSG Foot Switch with Two Contact Blocks – Complete Guide to FSGY1 / FSGY2 Series
Walk into any industrial workshop, welding bay, or machine tool area and you will often see operators controlling machines with their feet. When both hands are busy holding a workpiece, guiding a torch, or feeding material, a reliable foot switch becomes essential. The BCH FSG series foot switches, especially the two-contact-block variants such as FSGY1 and FSGY2L, are built exactly for these demanding situations.
What is the BCH FSG Foot Switch?
The FSG series from BCH Electric is a heavy-duty industrial foot switch range designed for continuous and rough factory-floor use. Models with two contact blocks (commonly referred to as FSGY1 or FSGY2 variants) give operators more switching capacity from a single pedal press compared to basic single-block switches.
These switches are commonly available in:
- Latch type – Pedal can be locked in the pressed position for continuous operation
- Guard type – Protective cover to prevent accidental activation
Why Two Contact Blocks Matter
A standard single-contact-block foot switch usually provides limited circuits. With two contact blocks, you typically get a combination of 4NO + 4NC contacts (four normally open and four normally closed).
This extra capacity allows one simple foot action to:
- Start a machine
- Send a signal to a PLC or interlock
- Control an indicator lamp
- Activate an auxiliary circuit
All of this happens without needing extra relays or complicated wiring, making the two-contact-block version far more useful in real industrial panels.
Key Features of BCH FSG Two-Contact-Block Foot Switches
- Heavy-duty construction suitable for industrial environments
- Moulded phenolic contact blocks for better heat and mechanical resistance
- Suitable for both AC and DC pilot circuits
- Available in Latch and Guard versions
- Conforms to IEC-60947 standards
- Designed for machine tools, welding equipment, rubber machinery, and special purpose machines
Common Applications
Machine Tools Lathes, presses, drilling machines, and milling equipment where operators need both hands free.
Welding Equipment Ideal when the operator is holding the torch or workpiece and needs precise control of the weld cycle.
Rubber & Tyre Industry Used on moulding, curing, and pressing machines for consistent, hands-free operation.
Special Purpose Machines (SPMs) Frequently built into custom machines from the design stage because of their reliability and multiple contact options.
Latch vs Guard – Which One Should You Choose?
| Feature | Latch Type (e.g. FSGY2L) | Guard Type |
|---|---|---|
| Main Purpose | Continuous operation | Prevent accidental pressing |
| Pedal Action | Can be locked down | Protected by cover |
| Best For | Long machine cycles | Busy or high-traffic areas |
| Operator Convenience | High for continuous processes | Higher safety against accidents |
Choose the Latch version when the machine needs to stay ON for longer periods. Choose the Guard version when accidental activation is a bigger concern.
Important Points Before Buying
- Confirm whether you actually need two contact blocks or if a single-block model is enough
- Match the contact rating with your control circuit voltage and current
- Check mounting dimensions and cable entry position if you are replacing an existing switch
- Prefer genuine BCH products for consistent performance and safety
Frequently Asked Questions
What does FSGY1 or FSGY2 mean in BCH foot switches? FSG is the series name. The number (1 or 2) generally indicates the contact block configuration. Models with two contact blocks provide higher switching capacity (typically 4NO+4NC).
How many contacts does a two-contact-block FSG foot switch have? It usually offers a combined 4 Normally Open (NO) and 4 Normally Closed (NC) contacts operated by a single pedal.
Can these foot switches be used for both AC and DC circuits? Yes. BCH FSG series foot switches are designed to handle both AC and DC pilot circuits.
What is the difference between Latch and Guard versions? Latch allows the pedal to stay pressed for continuous operation. Guard adds a protective cover to reduce the chance of accidental activation.
Which industries use BCH FSG foot switches the most? Machine tools, welding, rubber and tyre manufacturing, and special purpose machines are the most common users.
Is the FSG series suitable for heavy industrial use? Yes. These switches are built with robust materials and conform to IEC-60947 standards, making them suitable for demanding factory environments.
Where to Buy Genuine BCH FSG Foot Switch
For reliable performance, always source genuine BCH foot switches. You can check the latest availability and specifications of the BCH FSG Foot Switch on the official BCH website or through authorised industrial suppliers such as SB Smart.
Final Thoughts
The BCH FSG foot switch with two contact blocks is a practical, no-nonsense solution for industrial machines that need reliable hands-free control. Whether you choose the Latch or Guard version, the extra contact capacity, robust build, and compliance with international standards make it a dependable choice for machine builders and maintenance teams alike.
If you are designing a new panel or replacing an existing foot switch, the two-contact-block FSG models give you flexibility without adding unnecessary complexity.
