The B1 Basic Switches are ultra-compact, subminiature switches that excel in both commercial and military applications. These switches are noteworthy for their tiny dimensions, measuring only 0.300″ in width, 0.255″ in height, and 0.100″ in thickness, and are capable of reliably operating at low signal levels, or with up to 2 amps for a minimum of 25,000 cycles. Designed for an extensive mechanical life, exceeding one million cycles, these switches are durable with a rugged molded housing and molded-in terminals preventing solder flux penetration.
Key Features:
- Switch Size: Extremely compact design allows for usage in space-constrained applications.
- Lifecycle: The B1 series boasts a long mechanical lifecycle, specified at 100,000 cycles, and the B1-5 series at 1,000,000 cycles.
- Electrical Ratings & Life: These switches support various electrical ratings at sea level and 50,000 feet, with a guaranteed electrical life of 25,000 cycles.
- Temperature and Forces: They can operate between -55°C to +125°C, with a 6 oz maximum operating force and a minimum release force of 0.7 oz.
- Compliance: The B1 series is designed in accordance with MIL-PRF-8805/94 and is RoHS/WEEE/Reach compliant.
Material and Ordering Information:
- Materials: The switches consist of thermoset or thermoplastic cases, brass terminals with a gold over nickel finish, and silver contacts featuring optional gold for current-carrying requirements.
- Styles: Terminal options include double turret and PC pin terminals.
- Ordering: An OTTO part number code is used to specify the desired configuration, including construction grade, terminal style, operating force, and contact material.
B1-5 Basics with Integral Levers:
The B1-5 Series enhances the B1 Basic Switches by incorporating integral lever actuators, combining the switch and actuator into a single assembly for simplicity and cost savings. They feature different styles of levers including short straight levers, long straight levers, and short formed levers which influence the operational characteristics such as operating force, pretravel, overtravel, and movement differential.
Operational Characteristics:
- Performance: Each lever style has its own set of operational characteristics with precise measures for operating point, pretravel, overtravel, and movement differential.
- Customization: Other lever lengths and styles are available upon request to accommodate specific customer needs.
Both the B1 and B1-5 series are subject to specifications changing without notice, and the full product line features further details at OTTO’s website.
