C3AW Trigger switch for DC Brushless tools
Ensure miniature, dust tight, vibration resistance, shock resistance and durability
- C3AW achieves anti-dust (IEC IP6X) by mounting sealed boots and ultrasonic welding connection between cover cases.
- Strengthen contact shock resistance(There is not 100 μs or more of chattering within 3,000 m/s2)
- Durability for trigger is 300,000 operations or more
- Wire saving by connecting flat cable AWG#28 directly to the switch

Precautions for Correct Use
• When switches are actually used, unforeseen accidents may occur. Before using a switch, perform all possible testing in advance.
• Unless otherwise specified, ratings and performances given in this catalog are for standard test conditions (i.e., +5 to +35°C, and +45% to +85% humidity). When performing testing in the actual application, always use the same conditions as will be used in actual usage conditions for both the load and the oper- ating environment.
• Reference data provided in this catalog represents actual measurements from production samples in graph form. All ref- erence data values are nominal.
• All ratings and performance values provided in this catalog are the results of a single test each rating and performance value therefore may not be met for composite conditions.
• Output voltage changes due to the brush sliding along the top surface of the circuit board in the switch. When there is contact resistance between the circuit board and the brush, it goes into a state of high impedance, and the output voltage fluctuates. To prevent this from happening, a pull-up/down circuit can be implemented.
Check the level of output voltage fluctuations and compatibility of this circuit with your application to determine if this switch fits your needs.
