This momentary-contact pushbutton switch is very similar to our OMP Water-Proof Push Button Switch (Part No. OMP-EA467), except that it is not sealed against moisture. It can be used for any low-amperage momentary switching need (not for use as a starter switch), but when combined with the OMP Red Push Button Switch Guard Ring (Part No. OMP-X/181493, sold separately), it is ideal as a cockpit actuating switch for your electrical fire system. Since OMP fire systems locate the main switch on the power pack, this switch could be added to give the navigator an easy-access actuator, or mounted on the passenger side of the dash for corner worker access. Two clamp-type screw terminals on the back of the switch make connection easy, without the need for crimping or soldering.
