Where must a roller plunger switch be mounted on a door?

The roller plunger switch is designed to detect the position of a door, particularly if it is open or closed. Mounting the switch on the hinge side of the door, below the lowest hinge, is optimal for a few reasons.

Firstly, this position allows the switch to engage effectively when the door closes, as the roller plunger makes contact with the door frame. By placing it on the hinge side, it can also accommodate slight variations in door alignment, ensuring reliable operation. Additionally, this positioning minimizes the risk of accidental tampering or damage, as the switch is less exposed compared to a location on the lock side or the top of the door. Overall, mounting on the hinge side provides the best balance of function and security for door monitoring systems.
