Abstract :
The effect of total ionizing dose on a commercial optomechanical microswitch has been studied in this paper. One microswitch was irradiated using a Co60γ-ray radiation source at a dose rate of 330 rad/h to total dose up to 22.5 krad (Si). Little effect was observed in this device which is consistent with the technological design that does not contain insulators.
