A ceramic substrate for forming electronic tip parts. At least a pair of slits is substantially parallelly formed in the ceramic substrate for forming side electrodes, and a plurality of grooves are also formed in the ceramic substrate between the slits to cross the slits so as to define together with the slits divisions respectively for the individual electronic tip parts.

Ceramic substrates for tip electronic parts

In a multistage variable resistor consisting of rotary variable resistors stacked in a plurality of stages, the rod thereof being slideable in rotary and axial directions; a switch assembly for a multistage variable resistor having the central part of a dome movable contact movable by an actuator which is attached to the posterior end of the rod into contact with a stationary contact.
