20PW7 Lockout Pump Pressure Swichgages® are diaphragm-actuated, pump pressure-indicating gages, with built-in electrical switches. These switches include a front, semi-automatic lockout for startup override. On the 20PW7's, the low limit contact can be by-passed on start-up by pushing the lockout button. It holds the pointer away from the shutdown contact while the engine starts. The lockout will disengage automatically on rising pressure.
