Pin Switches

Pin switches

A pin switch is a spring-loaded plunger that presses in when a panel closes and pops out when it opens. It's how a security system knows whether your hood, door or trunk is shut, and it's a required part on most remote starter installs — the system needs to know the hood is up so it can refuse to start while someone is working under it.

Choosing one

Polycarbonate shafts handle engine bay conditions best, because they don't corrode. That's why they're the usual choice for hood pins.

Metal plungers are for locations that take physical abuse, and they reach further, which helps on deep gaps.

Waterproof boots matter anywhere road salt gets in. Water in the switch body is what kills most pin switches fitted in door jambs.

Telescopic switches adjust to the gap rather than needing the gap to suit them, which saves shimming when panels don't sit consistently.

Mounting brackets

Frequently there's nowhere flat to mount the switch, or the only surface faces the wrong way. Our flat and right angle brackets solve that for a couple of dollars rather than improvising something that rattles loose.

Where a pin switch won't work

If there's nothing for a plunger to press against, use a magnetic reed switch instead. For panels that lift rather than swing, such as hatches and camper shells, a tilt switch is the answer.
