Delay script to stop repeated api activation

Hi guys any ideas how i could modify the script below to prevent repeated activations upon extended switch. Only what I am finding on occassions is repeated api send messages. Would like to delay between each api send, maybe 2 seconds…

Please check the blink without delay example - this technique is a fundamental one to master many timing related issues.

Please add code tags next time - use the # button above the smileys.
