4. Contact reliability
Test conditions:
1. Contact current/voltage: 10
µA
100 mV 1 kHz
2. Cycle rate 20 cps.
3. Miscontact detection level: 1 mW (= 100
Ohm)
4. Detection method: Observation of all changeover
contacts
5. High temperature test
Test conditions:
Ambient temperature: 80°C
±2°C
Test method:
1. All contacts were switched for 100 operations on 2
A 30 V DC resistive load.
2. Samples then were exposed to 80°C temperature
for 5,000 hours, continuous
3. Contact resistance was measured with Hewlett-
Packard testing equipment.

NOTES
1. Prevention of vibration and shock
To reduce the likelihood of vibration and
shock, we recommend that you install so
that the contact action is not in the direc-
tion of gravity.
