SPECIAL PURPOSE SPECIAL PURPOSE SP Specifications Subject To Change Without Notice www.ottoexcellence.com 119 SPECIAL PURPOSE EXAMPLES OF APPLICATION SPECIFIC DESIGNS Park Brake This heavy duty push-pull switch was designed specifically for off-road heavy duty equipment.With an electrical life of 200,000 cycles and watertight to IP68S, the U2-326 park brake switch can withstand the most demanding applications. Push Force: 13.0 (58 N) +/- 50% Pull Force: 6.1 (27 N) +/- 50% Seal:Watertight to IP68S Electrical Life: 200,000 cycles Button: Aluminum alloy, red anodized Housing: Aluminum alloy, black anodized U2-326 Emergency Pushbutton To prevent inadvertent actuation, the operator’s finger must be directed into the protective cup before the OTTO high-force pushbutton switch can be energized. Designed as an aircraft jettison switch, this deep shrouded configuration can be adapted and applied wherever precise, no-error pushbutton switching is required. P1-90166 Flight Grip Rocker Switch Compact lightweight design for flight grips and other space sensitive installations. • Shallow mounting depth • ON-OFF-ON spring return to center • 2 circuit (N.O.–N.C.) switches • Utilizes OTTO B3 Basic switches per MIL-S-8805/101 • Low level switching (10mA @ 30mV) or standard rating (see B3 page) • Black anodized housing • Black molded button U2-351 Trigger Switch This precision trigger switch has an actuating force of 2.25 lbs. to make the first pole; 6.5 lbs. passing through a detent to actuate the second pole. Housing is black, button is red. Two models. Cat. No. MILITARY No. Width (inches) U2-016 M8805/111-01 0.641 +/- 0.016 U2-025 M8805/111-04 0.762 +/- 0.025 Rating: 7 amps @ 28VDC Door Interlock Switch Features a defeat function for special purpose applications. Normal logic requires the assembly to be mounted so the switch button is engaged by the actuator when the door is closed.When the door is opened, the spring disengages the actuator to turn off the machine. The assembly features an OTTO B3 double break snap-action basic switch. See B3 page. U2-053 Two-Step Sealed Trigger Switch This precision trigger switch offers two level operation with positive detent between levels. First level operates with 2.5 lbs. of force. It is moistureproof and dusttight sealed per MIL-PRF-8805, Sym. 2. The switch also provides electromagnetic pulse shielding. Trigger color is gray. Body is black. Features OTTO B3 basic switches per MIL-PRI-8805. Rating: 8 amps Resistive @ 28VDC U2-037 Hall Effect Rocker This Linear Hall Effect rocker switch will meet your needs when long life is required. Rated for 2.5 million cycles, it was designed for demanding applications and is fully protected against electromagnetic and radio frequency interference (EMI and RFI) up to 100V/M. U2-452 Custom Control Module The redesigned U2-472 utilizes HP7 Hall Effect switches and flex circuit with an on board connector, replacing traditional P9s and discrete wiring to increase life and speed up installation. • HP7 switches with 10 million cycle life • Flex circuit reduces assembly labor and cost • Customer termination via onboard connector • Designed and tooled to customer’s specifications • Finite Element Analysis (FEA) utilized to optimize assembly life U2-472 Edge backlighted for night vision operation available as P1-90158 Door Open Defeat Position FNR Compact, robust and reliable for grip or panel mount. The FNR is a 3-position switch that provides operator comfort by reducing the movement required to change direction and switch gears. Enhanced visibility with backlit lighting so switching is easy to see in poor or nighttime lighting. The internal switch has a mechanical life of 1 million cycles. HFNR-XX Hall Effect 3-position rocker with backlighting FNR-1002 Standard 3-position rocker with 36” 20 AWG wire leads
