HOOK SWITCH ACTUATOR

by Terry Dolezal

This article describes a unique switch actuator design to utilize a sliding bar type switch for telephone hook switch applications.

   In most telephone applications single or multi-pole make or break contacts are required to perform the hang-up switch function. The present design allows the utilization of sliding bar type panel mount switches that are available in a large number of configurations at reasonable costs.

   A pivot button is inserted onto the end of a sliding bar switch shaft to move the contact point between the switch and its actuator higher on the arc of the actuator (see Fig. 1). This allows for adjustment of switch travel distance. The switch then can be inserted into a printed circuit board and wave line soldered into place. The actuator then utilizes a unique hole configuration in the printed circuit board for mounting the actuator thereto (see Fig. 2). This then provides the attachment of the actuator and the actuator pivot point.
