Special material selection and construction details provide assurance that critical elements of the relay structure and mechanism will not be permanently displaced or damaged as a result of extremely high g level shocks. By virtue of their inherently low intercontact capacitance and contact circuit losses, the K Series relays have proven to be excellent subminiature RF switches for applications with frequency ranges well into the UHF spectrum. A typical RF application for the TO-5 relay is in handheld radio transceivers, wherein the combined features of good RF performance, small size, low coil power dissipation and high reliability make it a preferred method of T-R switching (see Figure 1 and 2). Temperature (Ambient) Shock The TO-5 relay, originally conceived and developed by Teledyne, has become one of the industry standards for low-level switching from dry circuit to 1 ampere. Designed for highdensity PC board mounting, its small size and low coil power dissipation make the TO-5 relay one of the most versatile subminiature relays available.

As this net holding force decreases, the SOFT IRON CORE A CORE B attractive force in the air gap of circuit A, which also AIR GAP SOFT IRON results from the flux of the permanent magnet, ARMATURE STATIONARY CONTACT becomes great enough to break the armature free of Core B, and snap it into a closed position against Core A. The armature then remains in this position MOVING CONTACT upon removal of power from Coil B, but will snap back to position B upon energizing Coil A. Since operation depends upon cancellation of a magnetic field, it is necessary to apply the correct polarity to the relay coils as indicated on the relay schematic. When latching relays are installed in equipment, the latch and reset coils should not be pulsed simultaneously. Coils should not be pulsed with less than rated coil voltage and the pulse width should be a minimum of three times the specified operate time of the relay. If these conditions are not followed it is possible for the relay to be in the magnetically neutral position.
