An electromechanical switch can be remotely opened by the interruption of electrical power to the switch for a minimum period of time. The switch includes a power terminal, a first switch (off) terminal, and a second switch (on) terminal. A first spring contact is coupled to the power terminal and spring biased to the off switch terminal. A second spring contact is coupled to the on switch terminal and is configured to receive the first spring contact in yieldable engagement. A lever is coupled to the first spring contact for manually moving the first spring contact to engagement with the first spring terminal and with the second spring contact. A solenoid is actuated in response to the interruption of power from the switch and flexes the second spring contact for releasing the yieldable engagement of the first and second spring contacts.
