A switch arrangement for interrupting signal flow on a microstrip transmission line includes an electromagnetically actuated conductive plunger extending through a hole in the dielectric plate on which the microstrip is formed. The strip conductor end adjacent the hole, and a spring conductive bridging element extends across the hole, fixed to one strip conductor and free to make contact with the other. The plunger is supported by a conductive diaphragm spring connected to the ground plane of the microstrip, thereby eliminating sliding contacts. When actuated, the plunger simultaneously lifts the bridging element free from the one strip conductor and short-circuits the other.
