P8 COMPACT PUSHBUTTONS COMPACT PUSHBUTTONS MOMENTARY OR PUSH-PULL ACTION, SHORTER BEHIND PANEL, SUBMINIATURE DOUBLE BREAK Makes and breaks every time OTTOs inherent rocking action Style Style Style P8-5 breaks welds and wipes contacts clean. Style P8-1 P8-3 P8-8 The P8 series pushbutton switches feature a shortened back panel depth while offering all the features of the regular size P1 and P3 series switches. P8 series switches offer vastly improved electrical and mechanical life under extreme conditions found in most military and industrial environments. On sealed models, a silicone boot operating on our patented rolling sleeve principle protects the contact area against Style contamination at the button area. This boot provides long life P8-4 and smooth operation over a wide temperature range. Sealed Style Style terminals protect the contact area from hostile environments P8-6 P8-7 and solder flux on both sealed and unsealed models. High contact force (120g/4.2 oz), low contact resistance (25m max) and short contact bounce are the result of our CUS snap-action mechanism. These characteristics guarantee exceptional current carrying capabilities over the life of the Standard Characteristics/Ratings: switch. With the optional low level configuration the P8 is well ELECTRICAL RATINGS: suited to interface directly to computers and other solid state Load Sea Level devices. 28VDC or 115VAC, 60/400Hz The P8 series is a quality precision snap-action switch designed Resistive 10A for use in panel boards, control sticks, computers, instruments, Inductive 5A pressure switches and other hand or machine operated Lamp 3A applications where rugged pushbutton switches are required. DWV 1050Vrms In addition, its precision permits the OTTO P8 to also be used Low Level 10mA 30mV as a limit switch. The P8 offers unique size, high electrical Electrical Life: 100,000 cycles (25,000 low level) ratings and a wide choice of mounting styles.
