Elevator Auxiliary Door Lock Elevator Secondary Door Lock DS Door Lock Contact Bridge Type Contact Switch Box

Elevator Auxiliary Door Lock Contact Switch is a key safety electrical component for landing door lock systems, working together with the main door lock contact to realize double interlock protection. It monitors whether the landing door is fully closed and the auxiliary lock is engaged reliably, preventing risks such as false locking, incomplete closing and door‑open operation of the elevator.  

Adopting silver alloy contacts, the switch features stable conductivity, anti‑oxidation and arc resistance. The normally‑closed safety contact design ensures the safety circuit cuts off automatically once the landing door is not locked properly, so the elevator cannot start. With flame‑retardant insulating housing and standard mounting holes, it is easy to install and replace, widely compatible with most passenger elevators, freight elevators and home elevators.Standard size, widely used for elevator repair & replacement.
