Cole Hersee Company, Boston, introduced momentary push-button switches for truck applications.
Two switches now have added lip-seals, making them waterproof and preventing ingress of moisture and contaminants.

The switches are permanently engraved "Engine Start" and "Engine Stop" into the surface of the button and will not wear off.

Both switches have two brass screw terminals with lockwashers and rugged diecast zinc housing with knurled aluminum facenut. The switches are keyed so that the switch or lettering will not rotate after it has been installed.

The switches are rated at 35A at 12V DC, 20A at 24V DC.
