Abstract: An escape release mechanism that serves as a supplementary means for unlocking a solenoid-driven locking switch. The escape release mechanism comprises a knobbed escape release switch that can be pressed by an operator from inside a protected industrial area to override the solenoid-driven lock. In response to a single-direction linear movement of the escape release key, a pin extends from the escape release mechanism in a direction orthogonal to the escape release key's linear movement. This forward movement causes the pin to displace the locking bolt of the locking switch. As the single-direction linear movement of the escape release key continues, the pin retracts from the locking switch out of the path of the locking tongue, allowing the tongue to be removed. In this way, the pin is both extended and retracted in response to a single-direction linear action by the operator.
