This limit switch is to be used as a replacement for the limit switch that was included with the Moyer Marine Temperature/oil pressure warning kit, in case your original limit switch should fail. The switch will close and send a signal to the alarm buzzer if your water temperature rises above 200 degrees.
NOTE: This water temperature limit switch should only be used as a replacement for the switch that came with the Moyer Marine warning kit. This limit switch is not a water temperature sender, and it should not be wired to a water temperature gauge.
NOTE: Except for warranty exchange, this switch is not returnable.
