Normally openTest with paddle in vertical position and the force (F) on rivet head (2).With an increase in flow (force), switch opens at ... 37 3 g (1.30 .11 oz) Paddle must travel a minimum of 1.27 mm (.050 in) farther [measured from (2) to the closed stop].With a decrease in flow (force), switch closes at a minimum of ... 31 g (1.09 oz) Paddle must travel a minimum of 1.27 mm (.050 in) farther [measured from (2) to the closed stop]. When the switch is installed in engine cooling system, the flow of coolant at cranking speed of the engine does not have enough force to activate the switch. When the engine is running at low idle the flow of coolant has enough force to activate the switch.4N3899, 6N1969, 6N5284
