Y2M Elevator Safety Bypass Switch Y2M113S10 (3-Position, EN 81-20 Compliant)

The Y2M Safety Bypass Switch is a critical maintenance component designed to meet the rigorous safety requirements of EN 81-20/50 standards. This 3-position cam switch allows authorized technicians to temporarily bridge (bypass) elevator door safety circuits during maintenance and inspection operations, ensuring efficient troubleshooting while maintaining strict control over the lift’s safety loop.

Technical Specifications: Y2M113S10 Bypass Switch

Product Description

The Y2M Bypass Switch is an essential tool for modern elevator control systems, particularly those adhering to EN 81-20 regulations. It is typically installed in shaft pit inspection panels, machine room emergency panels, and test stations. The switch provides a controlled method for bypassing door locking contacts, allowing technicians to move the car for maintenance purposes even when a door contact is open or faulty.

Operational Logic & Safety: The switch operates with a 90° rotary movement, offering clear tactile feedback between positions.

• Position 0 (Normal): All safety circuits are active. The elevator operates normally.
• Bypass Positions: Allows bridging of the Landing Door or Car Door safety circuits independently.
• Visual Warning: The integrated yellow transparent cover not only protects against accidental actuation but also serves as a visual warning that a safety device is present.

Maintenance Schedule: To ensure continuous safety, the switch itself requires periodic checks:

Important Safety Warnings:

• ⚠️ Authorization: This device must strictly be operated by trained and authorized elevator technicians.
• ⚠️ Reset: After maintenance is complete, the switch MUST be returned to the “0” (Normal) position to restore full safety loops.
• ⚠️ No Passengers: The elevator must never transport passengers while the switch is in Bypass mode.

Frequently Asked Questions

Q1: What is the primary function of this bypass switch in an elevator system?

The switch allows technicians to temporarily “bridge” (bypass) the safety circuits of the elevator doors. This is necessary to move the elevator car during maintenance or troubleshooting when a door contact is open or malfunctioning, as required by EN 81-20 standards.

Q2: Can the elevator run in normal operation while the switch is in a bypass position?

No. When the switch is in a bypass position, the elevator should only be operated in Inspection Mode or Recall Mode. Normal automatic operation with passengers is strictly prohibited and unsafe while safety circuits are bridged.

Q3: Where is this switch typically installed?

It is most commonly found in the control panel (machine room or MRL cabinet) or the emergency and inspection panels located in the elevator pit, allowing easy access for technicians during shaft work.

Q4: What happens if I forget to turn the switch back to “0” after maintenance?

If left in a bypass position, the elevator’s safety chain remains bridged, meaning the lift could technically move even if a door is open. This is a critical safety risk. Therefore, post-installation checks and strict maintenance protocols require verifying the switch is returned to “0” (Normal) before putting the lift back into service.
