ABSTRACT:
A silicon switch is provided. A silicon member biases a contact into abutment with an opposing contact located on a substrate such that a normally closed switch is provided. A plunger is provided which has an axis that extends along the axis of the two contacts. The plunger is secured by the silicon member in such a way that pressure on the plunger causes the switch contacts to open. When pressure is released, the bias built into the silicon member pushes the contacts back together. The switch is intended for use in a pen, for example in a white board application, where pressure of the pen to a marking surface forces the plunger upwardly into the pen and thus opens the switch contacts.
