In 1988, Electroswitch acquired the Type W Switches and Relays from Westinghouse
Corporation for the purpose of maintaining a high level of support and assistance to exist-
ing customers in the utility industry. Since that time, many changes have been made in
switch technology and these models have been replaced. However, Electroswitch continues
to offer the Type W Switches for customers needing replacements into existing systems
that would require panel rework.
Nameplates
Type W Switches are supplied with a standard black nameplate that can be engraved to your
requirements. Cir
cuit Breaker Control Switches have a cutout in the nameplate for a red and
green target indicator to show the last manual operation of the switch. Special engravings
should be indicated clearly at the time of order.
