SWITCHING CHARACTERISTICS

parameter

conditions/description

value

chattering

signal’s passage of time from 1.5 V to 3.5 V of each switching position (OFF to ON or ON to OFF)

t1, t3≤ 3 ms

sliding noise (bounce)

time of voltage change exceeds 1.5 V in code ON area. When the bounce has code ON time less than

1 ms between chattering (t1 or t3), the voltage change shall be regarded as a part of chattering. When

the code ON time between 2 bounces is less than 1 ms, they are regarded as 1 linked bounce.

t2≤ 2 ms

sliding noise

voltage change in code OFF area

3.5 V min

Notes:

3. Testing at 60 RPM.

4. Code OFF: The area which the voltage is 3.5 V or more. Code ON: The area which the voltage is 1.5 V or less.
