GENERAL INFORMATION
MICRO SWITCH NR Series Rocker Switches meet severe environment application
needs for a rugged, cost-effective manual switch. They combine the advantages of
toggle switch circuit versatility with pushbutton control.
Quality construction features include a premolded elastomer seal between the actuator and bushing andanelastomer cover/case gasketseal. Also, the terminal inserts are
molded into the high impact strength thermoplastic case.
Complete sealing of the switching chamber enables compliance with UL 508, paragraph 13.3 hosedown test. These switches can beused wherepanels aresubjected to
periodic splash and washdowns, such as are common to food and beverage equipment. They will also withstand exposure to heavy accumulations of eary morning dew
that may condense on the control panel in cabs of vehicles left outdoors overnight.
1 2 or 3 positions, maintained and
momentary action
1 Spring-loaded actuating mechanism
provides excellent tactile feedback
1 High impact strength, non-tracking
case enhances electrical stability
1 Temperature range: −40 to 71°C
(−40 to 160°F)
1 UL recognized, File E12252, Vol. 1,
Section 44
