Need an exit button for a door, gate, or other access control system? This uxcell switch is a simple and reliable option. It's a square, wall-mounted button in a sleek black color. You push it, and it sends a momentary signal (meaning it only makes contact while you're pressing it) to trigger your electric strike, magnetic lock, or other device to release and let you out. It's rated for AC 250V and 16A, so it can handle the electrical load for most standard access systems. The body is made from durable PC plastic. It has a classic key symbol on the button face. The dimensions are about 86mm x 86mm (that's a standard size that fits common electrical boxes) and 35mm deep. It comes with two screws for mounting. Just install it on or beside the door frame, wire it into your system, and you're set. A no-frills, functional switch for commercial buildings, parking garages, or secure areas in your home.
