Notice these are silver in color. This means they are NO = Normally Open. When pressure is applied the switch closes the internal contacts to complete the circuit. Both of these pressure switches are "on -off" design. Pressure turns them "on", no pressure they are "off" | Notice these are silver in color. This means they are NO = Normally Open.

| − | The pressure switch with 1 pole on it is self-grounding. This means the wire you hook to it is going to be grounded when pressure is applied to the switch. | + | The pressure switch with 1 pole on it is self-grounding.

| − | This design switch is not for external use on the outside of the transmission case. They have bleed holes in them. You need switches rated for external use on the outside to avoid oil leakage. | + | This design switch is not for external use on the outside of the transmission case. They have bleed holes in them.

This routes the 12 volt power through the switch to a single wire lock up solenoid. |
